CLARENCE N. CHILDS, OF LOWELL, MASSACHUSETTS.

ATTACIHVEEN'I FOR SPINNING-FRAMES.

To all whom it may concern:

Be it known that I, CLARENCE N. Claims, of Lowell, in the county of Middlesex and the Commonwealth of Massachusetts, have 'invented certain new and useful Improvements in Attachments for Spinning- Frames, of which the following description and claims, with the accompanying drawings, are a specification.

Like numerals on the drawings denote like parts.

This invention is an improvement in such attachments for spinning-frames as embody rotary hoppers or magazines, preferably such as are manually operated, in which ringspinning-travelers may be placed to be retained in bulk until they may be delivered a few at a time into a pan or receiver.

It is also an improvement'in such attachments for spinning-frames as embody boxes, pans, or receivers for ring-spinning-travelers from which they may be taken one at a time.

In cotton manufactories it is frequently necessary to change the number, that is the size, of the yarn that is being spun u on any given spinning frame, in order that t 1e yarn produced may be adapted to the changes in the varieties of cloth that the changing market demands. With every such change in the number and size of the yarn, a corresponding change in the number and size of the travelers that are used in spinning the yarn is necessary. When such a change needs to be made, the travelers that remain in the hopper must be removed therefrom and replaced by others of size adapted to the manufacture that is to ensue.

One of the objects of my invention is to facilitate the transfer of travelers-in-bulk to and from the hopper, to diminish the time necessary for the transfer, and to prevent the spilling of travelers upon the floor while the transfer is being made.

Another object is to make the dischargeopening of the hopper adjustable in width, in order that large travelers may not be too slowly and small travelersitoo rapidly discharged therethrough.

Whenever it is necessary to position a new traveler u on a spinning-ring, it is customary to put a ger upon a single traveler in the pan, to draw the traveler to and over the Specification of Letters Patent.

edge of the pan, and, as it passes the edge of the pan, to grasp it with the thumb in opposition to the finger that already touches it.

Simple as this process may seem, the travelers often fail to be thus grasped and fall upon the floor. The travelers are costly and their presence upon the floor is objectionable.

Still another object of my invention is to prevent travelers that are being removed from the pan and that fail to be grasped from falling upon the floor.

Figure 1 is a side-elevation of the entire attachment, with its cover omitted. Fig. 2 is a vertical section thereof at the line 22 of Fig. 3. Fig. 3 is a vertical section thereof at the line 3-3 of Fig. 1. Fig. 4 is a plan of so much thereof as is shown at the right of the line 44 in Fig. 1.

In the drawings, 1 is the stand, having, preferably, the semi-cylindrical stationary bearings 2 and 3 for supporting the hopper 4 through its journals 5 and 6. These bearings are beneath the vertical slots 7 and 8, which slots permit of the easy removal and replacement of the hopper, when it is desired to fill or to empty it. Preferably, integral with the stand, is: the foot 9, whereby it may be attached to the spinning-frame; the primary pan 10 into which the travelers fa a few at a time, from the discharge-opening 11 of the hopper; and, the secondary pan 12, placed beneath the edge of the primary pan, in which a traveler will be caught if, in the attempt to take a single traveler at a time from the primary pan and when the traveler has been drawn by the finger to the edge of the primary pan, the, operative fails to grasp the traveler between the thumb and finger, as is sometimes the case. The secondary pan is shown as a lip located just beneath the edge of the primary pan, but its construction can be varied without departing from my invention.

An opening is made from the outside to the inside of the hopper for the passa e of travelers-in-bulk. This opening should be large enough to pass travelers therethrough in such chains or bunches as are found in the packages in which travelers are commonly sold, and it should preferably be entirely unobstructed when it is uncovered or unstopped. For greater convenience in passing theltravel'ers through the opening without spilling them, I-prefer to give the passage a flaring mouth-piece. To economize space when a flaring mouth-piece is used, I prefer to enlarge one of the journals which support the hopper and open a passageway 13 there through for travelers-in-bulk. Preferably, I give'this'passageway flaring mouthieces 14 14, one at each end thereof, and ma re the mouth-pieces and the hollow journal integral with the hopper, although these details are not essentia to my invention. When travelers are not being passed through the openmg, I prefer to close it by some form of cover or stopper, such as a common cork 15, for the purpose of excluding fiyings and dirt. But any one of a variety of covers or stoppers may be used without departing from my invention. Preferably, I make one journal solid, and the solid journal long enough, out side of its bearing, to be grasped by the thumb and finger while one is rotating the hopper, and I fix the rib 16 diametrically opposite to the slot at the inside of the shell of the hopper.

I prefer to make the larger part of the hopper cylindrical in form, and to make a long slot 11 of fixed width in the cylindrical part of the hopper through which a few travelers ata time may escape therefrom. To adjust the width of the discharge-opening to the size of the travelers in the hopper I attach, preferably by screws 17 17, a curved slider 18 to the outside of the hopper. The screws pass through slotted holes 19 19 in the slider and the slider can be fastened to the hopper with one of its edges in such position as will narrow the discharge-opening to the desired extent.

It is evident that details of the described construction can be varied without departing from the essence of my invention.

I claim:

1. In an attachment for ring-spinningframes, in combination: a manually operated rotatable hopper; a journal for the support of the hopper having a passageway for travele'rs-in-bulk from the outside of the journal to the interior of the hopper; and, an open slot of fixed width parallel to the axis of rotation.

2.
